Place pineapple and zucchini in a bowl. Spray with oil and season with salt and pepper. Toss to combine. Heat a greased char-grill or a non-stick medium frying pan over medium-high heat. Cook pineapple and zucchini, in batches, for 1-2 minutes on each side until seared and just tender. Transfer to a plate.
